IMPROVEMENT it: ELASTIC CONNECTIONS FOR FLEXIBLE TUBING.

Specification forming part of Letters Patent No. 144,133, dated October28, 1873; application filed October 15, 1873.

To cl-llrchom it may concern:

Be it known that I, WILLIAM 13. S. TAYLOR, of the city, county, andState of New York, have invented a certain new and Improved ElasticConnection for Flexible Tubing, of which the following is aspecification:

The device in which my invention is comprised has been designed withspecial reference to the connecting of flexible, but inelastic,gas-tubing with the gasburner or the pipe'of a gas-stove. As a type ofsuch flexible but inelastic tubing, I refer to the tubing patented to meFebruary 21, 1865. This or other tubing made on awire coil is cheaper tomanufacture than the same quality of rubber tubing, and is usuallypreferred by dealers and consumers; but it has heretofore necessitatedthe employment of an expensive connection, so

. called, made of metal, or metal and rubber combined, which made thetubing too costly for common purposes; and, again, as all suchconnections asjust referred to are necessarily fitted on by themanufacturer, the dealer is required to keep on hand a large number ofpieces of different lengths, and even then does not always have the sizerequired by the purchaser.

By my invention the dealer need have but one long piece or coil oftubing, from which he may cut any required length, and fit onto it theconnection himself, the operation being very simple and easy. To effectthis very desirable result, I have devised an elastic connection,consisting of a tubular connecting-piece of vulcanized rubber or rubbercompound, with a varying internal diameter at one end, of a size to fitonto the tubing, and at the other end of a size to fit the gas-burner orthe pipe or nozzle of the gas-stove, or other article to which the gasis'to be conducted, substantially as herein described.

The accompanying drawing represents the manner in which my invention maybe best put into practice.

Figure 1 is a perspective view of the tubular connecting-piece detached.Fig. 2 is a longitudinal central section of the same represented asapplied and attached to the end of a piece of flexible gas-tubing.

The elastic connection consists of the vul canized-rubber tubular pieceA, having a varying internal diameter, the part a, of larger diameter,being designed to fit onto the end of the gas-tubing, and the part b, ofsmaller diameter, to be drawn onto the gas-burner or the pipe or nozzleof the gas-stove. The part a is of such length that, when fitted on thetubing, it may be bound at a point intermediate between its two ends bya cord, or its equivalent, onto the tubing, leavin g a sufficient lengthat the enlarged end to admit of this portion being turned back on thebody of the tubular piece, so as to cover and conceal the binding-cord.This arrangement is represented in Fig. 2, B being the flexible butinelastic tubing; 0, the binding-cord, and d the end of the elasticconnection, turned back so as to cover and con ceal the cord 0. A neatfinish can thus be given to the connection. I prefer to form theconnecting-piece A with an annular bead or flange, 6, at the end of parta, to allow the person applying the connection to more readily take holdof this end to draw it back over the cord, and also to give a betterfinish to the connection.

It will be understood that the exterior of the connectingpiece A may beof any suitable form or configuration, the requirement as to variationin its size referring only to its internal diameter.

Having described my invention, what I claim, and desire to secure byLetters Patent, is-

The elastic connection for flexible but inelas tic tubing, constructedand adapted to be fitted and secured to said tubing, as herein shown andset forth.

In testimony whereof I have hereunto signed my name in the presence oftwo subscribing witnesses.
